Achondroplasia is the most common form of dwarfism in miniature horses. Achondroplasia dwarf horses have normal sized bodies and heads, but noticeably smaller upper legs and ears. This form of dwarfism is an autosomal dominant trait. The pedigree shows the offspring of one horse without dwarfism, Individual 1, and one with dwarfism, Individual 2. The horses with achondroplasia are shorter. 1 2
Name: Kian Hamilton Period: 8th Using Punnett Squares to do a Monohybrid Cross You can use a Punnett Square to figure out the possible gene combinations of offspring using a Punnett Square. Remember, the stronger gene is dominant and the one that is masked is recessive. Dominant genes are always written with CAPITAL letters and recessive genes are always written with lower case letters. If both genes in the pair are the same, the trait is homozygous. If both traits in the pair are different, the trait is heterozygous. The genetic makeup of the individual is the genotype and the observable physical characteristics are the phenotype. Here is a list of dominant and recessive traits. You will be using these traits to predict the results of various crosses.

/a2 = 32 Familier, d. at least one girl? 3/32 = 968 Familier In squash, fruit color is determined by one gene and fruit shape by another independently segregating gene. The white fruit allele (W) is dominant to yellow fruit allele (w) and disk shape fruit allele (D) is dominant to round-shaped fruit allele (d). A cross between a white-colored, disk-shaped squash and a white colored, round-shaped squash resulted the following offspring: 31 white, disk; 29 white, round; 9 yellow, disk; 10 yellow, round.

Part 1: Consider three autosomal genes (E, F and G) present in a hypothetical species. The E allele results in male development, the e allele results in female development while the heterozygote develops as a hermaphroditic, sterile individual. The genes at the F and G loci show complete dominance, with the dominant alleles producing long tails (F) and black whiskers (G), while the recessive alleles produce short tails and grey whiskers, respectively. You cross a male with a short tail and black whiskers with a female that has a long tail and black whiskers. All the F1 individuals recovered have long tails, with some having black whiskers and others having grey whiskers. a) What is the sexual phenotype of the F1 offspring? ... b) Another batch of five offspring are expected from the same parents. What is the probability of the first offspring having a long tail and black whiskers?
